Nucleotidyl transferase proteins and the biological responses of Zea mays to abiotic stress

Nucleotidyl transferase proteins (NTPs) can modify the 3' ends of small RNA and mRNA and affect their stability. By analyzing the relationship between the domain of NTPs in Zea mays and the evolution of NTPs in Arabidopisis thaliana and Oryza sativa, 24 NTPs in Zea mays are identified, and the NTPs in Zea mays, Arabidopsis thaliana, and Oryza sativa are highly homologous and conserved. Sequence analysis shows that cis-acting elements of Zea mays NTP gene promoters contain many prmoter elements related to abiotic stress responses. Further analysis of real-time fluorescence quantitative polymerase chain reaction (RT-PCR) data shows that the expressions of NTP genes in Zea mays are induced by high salinity, drought, and abscisic acid stress, which indicates that NTPs may be involved in plant stress resistance pathway.
